Can I help you? is an "open-ended" question; it does not place any explicit limitations on what help the person being asked may request. There may be implicit limitations imposed by context; for example, a store employee approaching you while you are looking at the counter they are responsible for may ask the open-ended Can I help you?, but is really only inquiring if you need assistance with the products being sold at that counter.
Can I help you with {whatever}? is a limiting question; the person asking is explicitly specifying that their willingness or ability to assist is limited to {whatever}.
